Realization of PhysML: some subtleties

• Description of experimental setup is essential part

• Algebraic representation used changes in time
  [Vector: K ; (K_x, K_y , K_z); \vector{K), K_i , ..] or more important
  \int_D dD exp(\int L) equals Differential equation for for L

• test Dimension, Units, algebraic correctness, range (T larger zero).

• Physical Principles [e.g. no negative masses]

• Beaviour under transformation [connections different from tensors]
